View of a reproduction 10-stamp mill at the Western Museum of Mining & Industry, 225 North Gate Boulevard, Colorado Springs, Colorado. The mill was constructed in 1978 by museum staff using 19th century construction methods. Much of the equipment on display came from the Yellow Jacket Stamp Mill in Montezuma, CO. The structure is one of many exhibits at the museum, which opened in 1975 on the former Reynolds Ranch, a state register landmark.
